### Changes to Raft Protocol Support ### Changes to Raft Protocol Support
Consul 1.8 supported Raft protocols 2 and 3. Consul 1.9.0 now only supports Consul 1.8 supported Raft protocols 2 and 3. Consul 1.9.0 now only supports
Raft protocol 3 so before upgrading to Consul 1.9.0 users may have to first Raft protocol 3. Consul has defaulted to using Raft protocol 3 since version 1.0.0,
upgrade to a previous release supporting both protocol versions and upgrade so this should only impact users who have been using Consul prior to 1.0.0 and
the protocol in use to version 3. may have the `raft_protocol` config setting set to 2. Users in that position
should upgrade to a previous release supporting both protocol versions and
update their configuration to use Raft protocol 3 before continuing their upgrade
to Consul 1.9.0.
